HOLDING nn'vron.

Application filed 51113111, 1925. Serial No. 42,870.

Our invention relates to improvements in holding or fastening dev1ces,-and more particularly is adapted for use in connection with shade or globe holders for lighting fixtures, and is illustrated in the accompanying drawings in that association, though it will be readily understood that the invention is not limited thereto.

Referring to said drawings, Fig. 1 illustrates in side elevation, parts being broken away, a suitable form of shade holder with shade attached, the same embodying an ap- ,7

Fig. 7 is a fragmentary side view on an enlarged scale. 7

8 indicates a suitable form of shade or globe holder in conventional bell-like formation, and 9 the shadeor globe suspended therefrom. The shade holder is preferably made of thin sheet metal such asbrass, and is provided with a depending flange having an internal circumferential groove or channel 10, within which may be secured suitable'resilient projecting members 11 for supporting the outwardly projectmg flange or rim of the shade or globe. ,Opp'osite the said supports 11 may be secured springs 12 and 13, the formerbearing upon the cam l latch member 14, pivoted at 15, as shown,

and the spring 13 projecting the button 16 as shown. When the shade has been introdueed into the holder and rests upon the supports 11, the cam latch 1 1 is pushed from left to right looking at Flgs. 2, 3, and 4, therebyprojecting thespring or holder 12 inwardly and causing the free end of the spring 13 to ride successively into the notches between the teeth 17 of the latch. The num- 7 her of teeth traversed by the free end of the spring 13 will depend upon the diameter of the rim or flange of the shade or globe, a wide flange allowing the spring to only enter the first tooth. Vlhen it is desired to remove the globe or shade, it is only necessary to push inwardly upon the button 16 looking at Figs. 2, 8, and 4, thereby releasing the same from engagement with the teeth 17 and allowing the cam 14 to be rolled .leftwardly, thereby disengaging "the third support oft-he shade or globe and allowing the same to be removed.

In the modification shown in Figs. 5 to 7 inclusive, the .cam is indicated by thereference character 18, andmay be provided .with teeth, as shown, being eccentrically mounted upon the pin as indicated at 19. Inthe position shown in Fig. 5, the holder is clear to receive the shade, and in the position shown in Fig. 6, thefspring 12 of the holder has been thrown inwardly into supporting engagement with the rim of the shade or globe, securely holding the same in position, any slight variation in'the diameter of the same being taken up by the resiliencyin the spring 12. W hen the globe is to be'removed, the lever 20 of the cam is thrownleftwardly from the position shown in Fig. 6 so as to lay fiat against the rim of the shade holder as shown in Figs. 5 and 7.

If desired, the spring12 may be eliminated entirely, and the enlarged projection of the cam 18 may beused for the support of theshade or globe rim, but in that case it, may be found desirableto use a conventional form of spring for keeping the cam in normal position, or if desired, the lever cam 18 may be mounted with sufficient friction so as to remain in either position that it p is thrown, thus simplifying and cheapening the attachment.

Of course it will be understood vari-' ous modifications may be made in the con- 1. In a shade holder of the class described, a lower rim having two supports,

and a third support adapted to be moved in and out of supporting position, said third support adaptedto swing upon a substantially vertical axis, and of substantially cam-like formation, and a resilient member forengaging and disengaging said third member. v v V 2.1n a shade holder of the class'described, a lower rim having two supports,

and a third support adapted to be moved in "and out ofsupporting position, said third support adapted to swing upon a substanand a resilient member for engaging and disengaging said teeth.

3. In a shade holder of the class descr iloed5 a lower rim having tWo supports, and a third support adapted to be moved in and out of supporting position, said third support adapted to swing upon a substantially vertical axis, and said third support of substantially cam-like formation, and provided with teeth adapted to be engaged for holding the same in adjusted position, 15 and a resilient member for engaging and disengaging said teeth, said resilient member provided With a button for operating the same.

In testimony whereof We hereunto affix 20 our signatures.
